Why didn't Jiang Wen's "The Devil Comes" show?

Illegal operation, won the Cannes Film Festival without approval, and finally won the jury award. However, due to leapfrog management, it was banned. There is nothing wrong with the film itself. If it is step by step, the release is definitely not a problem. At present, the film "Where the Sun Rises" directed by Jiang Wen is still normal, and it will not be turned on until it is approved. It can be seen that the lesson has been learned, and the devil will be released sooner or later. Even if we don't let it go, we won't ban it in the future.
